Michael Christopher Phelan (born 24 September 1962) is an English professional football coach and former player who is currently assistant manager of Manchester United.
Born in Nelson, Lancashire, he spent most of his playing career at Burnley, Norwich City and Manchester United, with a short spell at West Bromwich Albion before retirement. While he was with Manchester United he also earned a single cap for England. In 2002, Norwich fans voted Phelan into the club's Hall of Fame.
Following the end of his playing career, Phelan moved into management. He first took a position as Gary Megson's assistant at his former club, Norwich City, before following Megson to Blackpool and then Stockport County. After Megson left Stockport, Phelan was hired by another former club, Manchester United, taking over as the assistant manager of the club's reserve team. Two years later, he was promoted to become Alex Ferguson's chief first-team coach, and in 2008 he replaced Carlos Queiroz as Ferguson's assistant manager. He remained in the position until Ferguson's retirement in 2013, when Ferguson's successor David Moyes replaced the entire coaching staff.
